A clearer starting point, not a fixed price list
This guide gives you a practical indication of the typical fee range and delivery time associated with our services before a formal quotation is prepared. Every project is different, and the final fee depends on the actual scope, complexity, available information, site conditions, level of documentation required and professional responsibility involved.
Why we publish ranges rather than fixed prices
Engineering services are not identical products. Two projects that appear similar at first glance may require very different levels of investigation, design, coordination, documentation or certification. Indicative ranges provide transparency while allowing the final proposal to reflect the real requirements of your project.
Indicative Fee Range
Typical fee ranges are shown excluding GST. The final fee is confirmed after we review the project scope and available documents.
Typical Time Frame
Time frames represent typical delivery periods for standard projects. Urgent, complex, staged or large-scale matters may require a different program.
Indicative service fees & time frames
Fees shown are exclusive of GST.

When comparing engineering fees
A lower fee is not necessarily a lower-cost outcome if the scope, deliverables or level of engineering input are different. Before comparing quotations, check whether each proposal covers the same site attendance, calculations, drawings, reporting, certification, coordination and revision requirements. A clear scope makes a meaningful comparison possible.
Important
These figures are guidance only and are not quotations, offers or fixed prices. Site attendance, authority fees, specialist consultants, testing, investigations and other third-party costs are not included unless expressly stated in a project proposal. Final scope, deliverables, time frame and fees are confirmed in the formal IA Engineering project proposal.
